Here is an article that is a bit old but discusses the start of things [1]. It would be a bit ironic if fracking tech helped get us further from using natural gas. I think the reality will be if this gets established we will see rapid improvement as scale comes on line so if it is remotely economical now it will be massively better in 5-10 years. Of course the 'if' applies.
